Aluminum Solid Panel Industrial applications

Aluminum alloy in the field of industrial applications increased year by year, but the use of aluminum components still have some problems, mainly poor wear resistance, the reason is the lower hardness, high friction coefficient, wear large, easy to strain and difficult to oil, Followed by the strength is not easy to deformation, and then in the presence of alkaline media and chloride ions in the environment is easy to be corrosion, which limits the further application of aluminum. Shanghai Min Jian Aluminum Company in the treatment of aluminum surface hardening problem, after the company's technology center and the joint research of Central South University, found a set of effective ways. We believe that anodic oxidation of aluminum alloy is an effective way to solve the above problems, in which hard anodic oxidation can improve the corrosion resistance of aluminum, wear resistance, heat resistance and insulation, film hardness up to HV400 or more, thickness Up to dozens or even hundreds of μm, easy to control the thickness, high dimensional accuracy, many parts can be directly assembled after processing, the film has a micro-hole, can absorb a variety of lubricants, breakdown voltage up to 2000V, with the matrix Solid, and therefore in the aviation, aerospace, ship, automobile, motorcycle, electronics, instrumentation, textile and machinery industry has a wide range of applications.

Technical principles and process: Technical principle: This process for the aluminum alloy electrochemical oxide film generation method.

Process: sealing treatment

Raw material → Molding → Degreasing → Etching → Pickling → Polishing → Oxidation → Washing

 Polishing the results of the level and the main technical indicators: the results of mature technology, equipment and advanced technology, film thickness can be determined according to workpiece requirements, high dimensional accuracy, many parts can be directly assembled to use, hardness up to HV400 or more, combined with the strength of the coating To be much higher, easy to use in the fall off. The wear resistance of the workpiece can be increased by more than 1 times. Low cost of technology. Market Feasibility: With the increase in the amount of aluminum alloy, surface strengthening requirements become increasingly strong, the current application of China is more hard chrome plating, but chromium is a shortage of materials, and the coating and the matrix is not strong, easy to use in the formation of abrasive particles Wear, combined with environmental pollution and other issues difficult to solve. In industrialized countries, hard anodizing has been widely used, such as the Japanese automotive industry, engine piston, cylinder, injector plunger, motorcycle carburetor needle valve, piston and so on through the hard anodized , But these parts are not handled directly to use these parts, affecting the product quality and workpiece life. Hard oxidation in the country is still in the transformation from scientific research to production stage, cars, motorcycles and other industries have begun to understand its superiority, and some manufacturers are seeking this technology, market prospects and considerable economic benefits. The following are the same as the "

Implementation conditions: Major equipment: working slot group, oxidation power system, tank circulation, filtration system, heat exchange system, air mixing system, exhaust system.

Market prospects: With the increase in the amount of aluminum alloy, surface strengthening requirements become increasingly strong, the current application of China is more hard chrome plating, but chromium is a shortage of materials, and the coating and the matrix is not strong, easy to use in the formation of abrasive wear , Coupled with environmental pollution and other issues difficult to solve. In industrialized countries, hard anodizing has been widely used, such as the Japanese automotive industry, engine piston, cylinder, injector plunger, motorcycle carburetor needle valve, piston and so on through the hard anodized , But these parts are not dealt with in China and direct use, affecting the quality of products

Quantity and workpiece life. Hard oxidation in the country is still in the transformation from scientific research to production stage, cars, motorcycles and other industries also began to understand its superiority, and some manufacturers are seeking this technology, market prospects and economic benefits.
